Application filed January 18. 1900. serial No. 1,893. (No model) -ble for the stacker capable of being operated by a person standing at the side of the ma-' chine upon the ground or floor'or on a platform of the machine, the operation of the turn-table being such that the stacker may be quickly moved from an extreme right to an extreme left position or anyposition between such points. I

Another object of the invention is to provide means whereby an operator standing on the ground orfioor at the side of the thresher may turn the hood in any direction and make the delivery or discharge tube long or short, as desired.

A further object of the invention is to so construct the stacker that the delivery-tube may be reduced in length to such an extent that the thresher,with the stacker applied and ready to work, may be conveniently placed in a barn or other inclosure and operated therein. v

Another object of the invention is to re- 7 duce the friction of all-the working parts by the application of ball or roller bearings 2 nd to provide a simple mechanism which ill permit the delivery or discharge tube to be raised or lowered and the hood to be brought close to the ground when necessary.

The invention consists in the novel con struction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

'Figure 1, is a perspective view of the improved stacker applied to the rear end of a threshing-machine, the delivery or discharge tube .1 Ling'shortened, Fig. 2 is a partial side elevation of the rear portion of a threshingmachine and a longitudinal vertical section through the stacker, the delivery or discharge ,1

tubebcing extended. Fig. 3 is a detail side elevation, parts being in section, of abearing for the fan-shaft, illustrating said shaft in position in thebearings; and Fig. 4 is a horizontal section through the fan-casing of the 1 attachment, the fan appearing in plan view.

A represents a thresher of any suitable or approved construction, and B the platform, which is located at or near the bottomthei'eof and extends rearwardly from the bodyiofthe thresher.

0 represents an outlet at the bo'ttomiofth e'. rear projecting portion of the threshing-machine, and D. represents-a turntable-which is carried by the platform B. Thiszkturn-ta- 1 ble consists of a ring-gear l), having exterior teeth, and the said gear is supported-upon;

rollers 11, placed insuitablebearings sn ported by the platformB, and rollers 1 2,"lik

wise supported by the platform through thei medium of studs 13, engaged with the-inner surface of the ring-gear 10; as shown in- Fig. 4,'preventing said gear from having side'movement.

A fan-casing 14 is located abovethe rihga" gearvlO, being connected thereto bypins'lf as shown in Figs. 2 and :4, audthis fan-cas' ing is enlarged. at one side, as shown particularly in Fig. 4, and by thusincreasing the fan casing at one side the air is less confined; and

less power is required to run the fan-. The

fan-casing 14 is provided with a throat'lfi, errtending rearwardly beyond the rear of the threshing-machine, and the fan 17,.located within the casing, may be of any suitable or approved construction. It may here be remarked that the enlarged portion of the fancasing is that portion which is adjacent; to the throat 16.

The fan 17 is mounted upon ashaftlS, and.

this shaft is held to turn inbearings v1.9 and 19, formed upon a bracket 20,'which bracket issecured to the platform B and usually ex-jz ten'ds below the sam'e,as shown in Fig'. 2, the

bracket being shown in detail inFig. 3. The

upper bearing 19 is provided with a recess or enlargement 20 at its upper end, adapted to receive a cone 21, secured on the shaft 18,

which cone rests; upon rollers or balls22,

placed in the oottomof the enlargement or:

delivery-tube E. The opposing faces of the g 19 is provided with enlargement 23 at its bottom portion, and a cone 24 is held on the shaft 18 within this lower enlargement by a suitable nut 25, and-the cone 23 engages with rollers or balls 26, which in their turn engage with the upper wall of the said recess 23 of the bearings. Thus it will' be observed that the shaft 18 may possible amount of friction. The driving-pulley 27, which is socured to the shaft 18 between it bearings, may be connected with any suitable source The turn-table is operated in the following manner: A shaft26 is mounted in suitable bearings 27, secured on the platform B, and 'theshaft 26 is provided with a hand-wheel 28 atone end and with a beveled pinion 29 at its :opposite end.- This beveled pinion 29 meshes with a beveled gear 30, and the'beveled gear 30 is secured to a vertical shaft 31, suitshaft- 3l-carries a pinion 32, which meshes with the teeth of the ring-gear 10. Theth roat 16 of th'e-fan-casing is provided with a sleeve 32, which is held against turning, and the rear end' of this sleeve is enlarged beyond the diameter of the--throat 16, asshown particuis carried by the turn-table, and this discharge or delivery tube is constructed in telescopic sections are usually employed-namely, an inner or forward section e, an intermediate section Te, and an outer or rear section 6 The forward end ofv the forward'section e of the condliching-tube isflmuch larger in area than th area' of the sleeve 32, attached to portion of the conducting-tube is connected by pivots 34 with the said sleeve 32, as shown in Figsl and' 4. 1

Ahood 35 is connected'by a hinge 36 with. a short tube a and such short tube-constiwith the hood, and a rope 38 is attachedto' this arm and is carried toany convenient ground or from a threshing-machine. The short tube a, at its forward end, is provided with anrexternal gear39, and an annular flange '40 is extended from the forward face of thesaidgear, the flange-4O being carried ever a 41. formed upon the a rteniorcf the -rearportion of the rear sections v of the flange iO and collar 41 are grooved to receive balls or rollers 42. Thus it will be observed a that the short'tube-section 0 carrying the. hood 35, maybe turned'upon the deliverytube E with verylittle friction.

The hQOdrSBCtlOD of the dischargetube E is adapted tobe turned bya-p'er nii'standing ion 15 meshes with the gear 39, which pinion 'hood. the throat of the casing, and this enlarged hearing 43, constituting an upper extension of the collar 41, as shown in Fig. 2. The body portion 44 of the shaft 44 is polygonal in cross-section, except at the forward extremity of the said shaft, where a circular enlargement 46 is formed. The polygonal section 44-of the shaft 44 is adapted to enter a tubular shaft 45, whose rear end is interiorly polygonal; but the remaining portion of the interior of this tubular'shaft 45 is circular and of larger diameter than the polygonal portion, so that the circular section 46 of the shaft 44 will strike a shoulder on the tubular shaft 45 when the. sections of the discharge tube havebeen-drawn out to their full extent. The tubular shaft 45 is exteriorly polygonal and telescopes in'a second tubular shaft. 47, interiorly polygonal and exteriorly circular. This shaft 47 is journaled in an extension 62 from a collar 61,'ext eriorly and'integrally formed-upon the forward end of the intermediate section c of the discharge-tube, and the forward end of the shaft 47 is journaled in an extension 49 from a collar 50, lo.- cated exteriorly on the forward section eof the discharge-tube at its enlarged portion, as is also shown in Fig. 2. The extension 49 is provided with an auxiliary bearing 51; in which a shaft 52 is mo unted to turn, provided with a hand-wheel or crank, and this shaft carries a beveled pinion 53, which meshes with a similar pinion '54, secured to'the foru'ard end of the tubular shaft 47,'as shown in Fig. 2. Thus it will be observed that the conducting or delivery tube E may be made as short as desiredwithout interfering with the action ofthe operating shafts for the The adjustmentof the sections. of thedischarge or delivery tube E is effected through the medium of a feed-screw 55. This screw is held to turn ina threaded aperture made in a lower extension 56 from-a collar 57, which is secured externally to the forward end of the rear section e of the conducting-tube E, and the upper portion of this collar56 is provided near one side with an opening 58, as\

shown Figs. land 2. The other end'of 115 the feed shaft or screw is held to turn loosely, but without and movement, in a downward projection 59 from the collar 50, secured to the forward end of the lower section e of the discharge-tube. The forward end of the feed screw or shaft 55 is provided witha handwheel-(if), sothat tlre'said-straft orscrew may be readily manipu-lated.- The conducting tube Emay be raised or lowered'as far as may be desired by placing a pulley 63 'i ti the up- .per portion of the extension 62 of the collar.

also provided usuallywith acrank-hand.le'68.. I p v section 6 will cause the inte media'teor 'tral 'sectionl to be alsodr'awn' out;

roller 69 engages withthe bottcm of the ntermediate section e of "the conducting-- 'tube E, the roller being carried by an'arm fo'rwardly extended from the forward collar 56 of the rear section of said conducting-tube,

and the forward collar 61 of the intermediate section e of this cond noting-tube is'in its turn provided with a forwardly-extending arm carrying a frietion-rollerti), whichfengages forward sectiori' e 'of the conducting-tube. These'rollers Gil-and '69 serve materially to support the secijt-ionslof "the conducting-tube at their lower portions. {The upper portions of thesections of 'theconducting-tube E are supported usua'.lly, as shown in Figs. 1 and 2. This support consists in securing a rod 70 to the upper portion of the collar 41 at the forward end of 'tlie rear section-e of the said delivery or conducting tube, and carrying the said rod to the rear collar 57 of said rear section and forward of the said collar, the forward end of the rod 70, which extends downward, being provided to engage with'thebottom portion of a rod collar, and the rod extends loosely through 72, and this rod 72 is secured to the upper portion of the collar til on the intermediate section of the delivery-tube, at one side of said the upper portion of the collar 57, and its rear end is provided with a roller 73, which engages with the under surface of the rod 70, as shown in Fig. 2. At the opposite, side of the conducting-tube a rod 74: is secured to the upper portion of the collar 61, extending forwardly of said collar and downward, carrying at its downwardly-extending end a friction-roller 75, and the rear end of the rod 74: is plain and is adapted to extend through the opening 58 in the collar 57. On the same side of the delivery-tube a rod '76 is secured to the upper portion of the forward collar '50, and this rod is free to slide through the upper portion of the collar 61 and is provided at its rear end with a roller 77, engaging with the bottom of the rod 7t, as shown in Fig. 2. When the sections of the delivery-tube are fully telescoped, the roller 77 passes through the opening 58 in the collar 57, as shown in Fig. '1. Then the parts are to be telescoped, the screw-shaft '55 is turned in one direction, whereupon through the rod. connection between the rear section e of the said tube and the intermediate section- 6 of said tube the central or intermediate section 2 is made to slide forwardly over the forward section e, and when the intermediate or central section is properly seated the rear section 6 will telescopover the central or intermediate section, and -a like telescopic action takes place between the sections of the shaft employed to turn the hood. When the sections of the delivery-tube are to be extended, the rear section is first carried rearward, and as the forward collar of that section engages with" the Having thus. described 'mydnven 1.
